Modelling Weak-Coherent CV-QKD Systems Using a Classical Simulation Framework
Sören Kreinberg, Igor Koltchanov, Piotr Novik +5
Due to their compatibility to existing telecom technology, continuous variable (CV) weak coherent state protocols are promising candidates for a broad deployment of quantum key dis…
Thresholdless transition to coherent emission at telecom wavelengths from coaxial nanolasers
Soren Kreinberg, Kaisa Laiho, Frederik Lohof +5
The ongoing miniaturization of semiconductor lasers has enabled ultra-low threshold devices and even provided a path to approach thresholdless lasing with linear input-output chara…
Adding artificial noise for code rate matching in continuous-variable quantum key distribution
Sören Kreinberg, Igor Koltchanov, André Richter
The reconciliation step of continuous-variable quantum key distribution protocols usually involves forward error correction codes. Matching the code rate and the signal-to-noise ra…
Mutual coupling and synchronization of optically coupled quantum-dot micropillar lasers at ultra-low light levels
Sören Kreinberg, Xavier Porte, David Schicke +5
In this work we explore the limits of synchronization of mutually coupled oscillators at the crossroads of classical and quantum physics. In order to address this uncovered regime…
Quantum-optical spectroscopy of a two-level system using an electrically driven micropillar laser as resonant excitation source
Sören Kreinberg, Tomislav Grbešic, Max Strauß +6
Two-level emitters constitute main building blocks of photonic quantum systems and are model systems for the exploration of quantum optics in the solid state. Most interesting is t…
Emission from quantum-dot high- microcavities: transition from spontaneous emission to lasing and the effects of superradiant emitter coupling
S. Kreinberg, W. W. Chow, J. Wolters +6
Measured and calculated results are presented on the emission properties of a new class of emitters operating in the cavity quantum electrodynamics regime. The structures are based…
Photon-Statistics Excitation Spectroscopy of a Single Two Level System
M. Strauß, M. Placke, S. Kreinberg +5
We investigate the influence of the photon statistics on the excitation dynamics of a single two level system. A single semiconductor quantum dot represents the two level system an…
